Last week, I delivered a presentation about the recent report Web3D: The Next Major Internet Wave at the vBusiness Expo in Second Life. I'll share some of my experiences and observations, as I'm sure that during the coming year many of you will be invited to present at or attend virtual conferences and meetings -- if you haven't already. These tips may prove helpful.

Teradata has taken the big plunge. Yesterday, as long rumored, it launched the first commercial solutions in its broad portfolio to be explicitly positioned as data warehousing (DW) appliances. Specifically, it announced the new Teradata 550P, Teradata 2500, and Teradata 5550 platforms, which join the established Teradata 5500 platform in the vendor's market-leading enterprise data warehousing (EDW) solution family.

Informatica today announced its planned acquisition of Identity Systems, a software company offering advanced entity resolution and matching capabilities, with a specialization in cross-language matching.

Informatica acquires Identity Systems from Nokia for approximately $85 million.Nokia purchased Identity Systems as part of its acquisition of Intellisync in early 2006 and Identity Systems has operated as a wholly-owned — and more important — autonomous — subsidiary of Nokia ever since. Not surprisingly, Nokia didn't see identity resolution and matching as part of its core mobile phone strategy and I expect the folks at Identity Systems will be happy with this change of ownership.

If you're an analyst, one of the nice things about having a blog is that you can provide out-of-band commentary on, or elaboration of, points raised in your formally published reports. That way, you don't need to clutter up the body or endnotes of the published reports with digressive — albeit important — discussions.

This present post elaborates on the discussion of enterprise data warehouses (EDW) in my latest research report: "Appliance Power: Crunching Data Warehousing Workloads Faster And Cheaper Than Ever." As I was writing this document, it occurred to me that a formal, nuanced definition of EDW was important — but not within the proper scope of that particular report.

As is clear from the general pattern of my Forrester I&KM blog posts, I'm closely tracking the penetration of complex event processing (CEP) into the world of real-time BI and data warehousing (DW). I'm working on a report now providing best practices for real-time DW, which will be available later in Q2. I'll follow up with a trends document on CEP for real-time BI in Q3.
